Purpose

Pattern turns the timeline and a scale into a performable musical part. It covers several roles, from lead melody and bassline to chord pulses, call-and-response phrases, orbit walks, and scatter patterns, all with artist controls for density, accent, humanize, tie, mutation, voicing, and octave. It is a flexible procedural sequencer for building parts without writing every note.

Use

Wire a timeline clock into Input 0 and a scale into Input 1. Choose a Mode for the type of part, pick a Pattern shape and Rate, then route the out voices to an instrument. For a hand-built phrase, set Pattern to custom and dial the eight Degree controls.

Inputs and outputs

• Input 0: timeline timeline clock. Required.
• Input 1: scale scale context. Optional, keeps the part in key.
• Output 0: out emits the pattern as note voices.

Controls

• Mode: part role. melody, bassline, chord_pulse, call_response, orbit, or scatter.
• Pattern: shape such as custom, ascending, descending, pendulum, triad, pentatonic, neighbor, answer, or euclid.
• Rate: step speed from half_step to quad.
• Rootnote: base pitch.
• Patternlength and Stepoffset: number of steps and where the pattern starts.
• Gate, Velocity, Density, Accent: note length, level, how many steps fire, and emphasis.
• Humanize, Tie, Mutation: timing looseness, note ties, and gradual change.
• Spread, Voices, Range, Inversion: voicing width, voice count, octave range, and inversion.
• Degree1 to Degree8: the scale degrees used by the custom pattern.
• Seed: repeatable random elements.

Notes

• Use custom with the Degree controls to write an exact phrase, or a preset Pattern for instant results.
• Mutation slowly evolves the phrase over time, which is good for long generative sets.
• The same node can act as melody, bass, or chord part just by changing Mode.
